Be aware that some features impact whether an upgrade is disruptive or nondisruptive:
–
Fibre Channel Ports: Fibre Channel ports can be nondisruptively upgraded without affecting traffic on the ports. See
for the nondisruptive upgrade path for all NX-OS and SAN-OS releases.
–
Gigabit Ethernet Ports: Traffic on Gigabit Ethernet ports is disrupted during an upgrade or downgrade. This includes
the Gigabit Ethernet ports on the MSM-18/4 module, SSN-16 module, MDS 9222i, and MDS 9250i switch. Those
nodes that are members of VSANs traversing an FCIP ISL are impacted, and a fabric reconfiguration occurs. iSCSI
initiators connected to the Gigabit Ethernet ports lose connectivity to iSCSI targets while the upgrade is in progress.
